QNAP Snapshot Agent enables QuTS hero to take application-consistent snapshots of iSCSI LUNs on Microsoft servers, and iSCSI LUNs and NFS shared folders on VMware. Application-consistent snapshots record the state of running applications, virtual machines, and data. When QuTS hero takes a snapshot, QNAP Snapshot Agent triggers the following actions:

• Windows: The server flushes data in memory, logs, and pending I/O transactions to the shared folder or LUN before the snapshot is created.

• VMware: The server takes a virtual machine snapshot.
